This MATLAB exercise computes four types of short-time autocorrelation of a speech analysis frame and, in cases that are determined to represent voiced speech frames, estimates the pitch period of the current analysis frame for each of the four types of short-time autocorrelation. The exercise also processes the speech signal on a frame-by-frame basis, and estimates and plots the pitch period contour of the entire utterance.
